Can anyone tell me the exact differences between the L3 and L4?
- 435 vs 490 HP, same engine but the transmission can handle more power.
- 4,150 vs 4,450 Lbs MTOW
- Slightly different fuel burn sequence with minor changes in the fuel system.
- Slightly different limitations, like in N2/NR
- Some L4's have a High Altitude Tail Rotor Kit installed.
- The L4's come with a K-Flex main driveshaft as standard equipment.
- Some L3's don't have a FWD Fuel Qty switch, although all L4's do.
I can't remember any other differences, but mainly that is it, they are almost identical, and at High DA's I would much rather go on the L3 as the L4 gets a little dangerous with the TR situation.
